skge: add GRO support
- napi_gro_flush() is exported from net/core/dev.c, to avoid an irq_save/irq_restore in the packet receive path. - use napi_gro_receive() instead of netif_receive_skb() - use napi_gro_flush() before calling __napi_complete() - turn on NETIF_F_GRO by default - Tested on a Marvell 88E8001 Gigabit NIC Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
